Explanation:

On April 20, 1902, Marie and Curie with success isolate radioactive  metallic element salts from the mineral uranium ore in their laboratory in Paris. In 1898, the Curies discovered the existence of the weather radium and metallic element in their analysis of pitchblende. One year once analytic  radium, they might share the 1903 Nobel prize in physics with French soul A. Becquerel for his or her groundbreaking investigations of radioactivity.

Marie Curie was born Marie Sklodowska in Warsaw, Poland, in 1867. The girl of a physics teacher, she was a talented student and in 1891 visited study at the university in Paris. With highest honors, she received a degree in physical sciences in 1893 and in arithmetic in 1894. That year she met state capital Curie, a noted French man of science and chemist who had done vital add magnetism. Marie and Pierre married in 1895, marking the start of a scientific partnership that will accomplish world renown.

1. Which criteria are used to classify amphibians into orders?

Answers

Answer:

They are classified into three orders: frogs and toads, salamanders and newts, and caecilians.

Approximately 8,100 species of living amphibians are known. First appearing about 340 million years ago during the Middle Mississippian Epoch, they were one of the earliest groups to diverge from ancestral fish-tetrapod stock during the evolution of animals from strictly aquatic forms to terrestrial types. Today amphibians are represented by frogs and toads (order Anura), newts and salamanders (order Caudata), and caecilians (order Gymnophiona). These three orders of living amphibians are thought to derive from a single radiation of ancient amphibians, and although strikingly different in body form, they are probably the closest relatives to one another.

17. What causes evaporation?
O Air that is unsaturated with water vapor comes into contact with the surface of the water
O Air that is cooler than the water comes into contact with the surface of the water
O Air that is warmer than water comes into contact with the surface of the water
O Air that is supersaturated with water vapor comes into contact with the surface of the water in

Answers

the answer is the first one

Evaporation occurs when air that is warmer than water comes into contact with the water's surface, hence option A is correct.

What is evaporation?

As a liquid transforms into a gas, evaporation, a sort of vaporization, occurs on the liquid's surface. For instance, a high concentration of the evaporating substance in the surrounding gas significantly slows down evaporation when humidity affects the rate of evaporation of water.

It takes in moisture from garden soil as well as the biggest lakes and seas, and the level of the water will decrease when it is heated by the sun.

Therefore, solar energy, or heat from the sun, is what causes the evaporation process to occur, hence option A is correct.

if you step on a sharp object muscles in your leg will rapidly put your foot away.


what is the correct term for this type of reaction?​

Answers

Answer:

Explanation:

Sharp object the reaction is a reflex its involuntary and it doesn't involve ur brain it protects u from damage.So u step on the sharp object whihc is a stimulus so the reaction is reflex its quick and automatic.

Hope this helps

Reflex arcs can also be more complex. For example, consider what happens when you step on a sharp object. As in the example above, a sensory (pain) neuron carries an impulse to an interneuron in the spinal cord. The interneuron synapses with motor neurons which pull your foot away from the sharp object, just as in the example above. However, if that was all that happened you would probably fall over! The interneuron also synapses with motor neurons which control the muscles of the other leg. These muscles adjust your position so you do not fall. The interneuron synapses with still other neurons, which carry the information about what has happened to the cerebellum (which coordinates the muscular activities) and the cerebrum, so that you become "conscious" of what has happened and can take further voluntary action.
